Application filed February 28, 1918. Serial No. 219,184.

Thls invention relates to carbon sheets or' duplicating material to be usedbetween the work-sheets in manifolding upon ii-type- Writing machine. The inventlon 1S es ecially lntended for use in connection with combined typewriting and computin machines which perform addition and su traction.

It is customary in such machines to use a, bichrome ribbon having black and red colorstripes, and to connect the ribbon mechanism to the computing mechanism in such a Way that any numbers that are subtracted are typed in red upon the work-Sheet; thus the Sheet bears its own evidence that such numbers have been subtracted by the computing mechanism.

This ex edient, however, has been necessarily limited to the single sheet upon which the ribbon directly prints; and the difiiculty has existed that on the carbon copies, which are almost invariably manifolded at 'the same time as the ribbon'copy, there is nothing 'to indicate whether any particular number has been either added or subtracted by the computing mechanism.

Many eiforts have been made to avoid this difiiculty and to provide that the several carbon copies shall also indicate for themselves whether any given number appearing thereon has been added or subtracted. For this purpose it has been proposed to have large figure types in the typewriting machine, which are called into use only When subtraction is being'performed by th@ computing mechanism; so that the carbon copies will show by the lai'ge figures thereon that certain numbers were subtracted.

It has also been proposed to print a special sign before each number that is to be subtracted, so that. the carbon copies shall give evidence accordingly.

It has also been proposed that a Special mark shall be printed under each digit that is typed, where such digits are subtracted.

The object of my invention is to provide for a distinction to be made between the added numbers and the subtracted numbers upon the carbon copies of the main o'r other work-Sheet, without necessitating the use of a Special set of types, or a Special sign or other Special device or mechani'sm in the tyewnting machine.

o attain this end, I provide means whereby the .numbers that are subtracted are A typed inred on thecarbon copies, While the remammg numbers and data are typed n black. For' this purpose, all numbers that are to be subtracted are typed in a column or' columns by themselves as and the carbon sheet is provided with a vertical stripe of red in register with such subtraction column, so that any numbers written'in said column shall appear in red upon the carbon Sheet; the remaining portion of the working carbon being black.

For the purpose of keeping the carbon Sheet ln accurate alinement and register with the work-sheets,-so that no numbers shall appear partly in red and partly in black upon the manifo'id copies, I provide the Carbon, preferably. upon both edges, with rows of perforations which match the perforations in the work-sheets, and by means of these perforations all ofthe sheets are impaled upon collating pins usually rovided in the typewriting machine, These perforations are made in side margins or borders of the Carbon sheets, whichare not coated with. the Carbon or transfer material; and the perforated borders of the carbon Sheet may be reinforced, as by folding over the edge, so that the material is of double thicknc where the holes are punched through, as conducing to the longevity of the Sheet. Since the Sheet is usually extremely thin, the extra thickness produced by the fold is not an objection; and th'e accumulated efi'ect of these reinforcing folds will not prove ob'ectionable in ordinary use, smce the extra t ickness of the borders of the small number of carbon sheets used in making the few copies customarily made at one Writing is' not noticeable or objectionable.

In the accompanying drawings,

Figura 1 is a perspective view to illustrate the use of my invention'in an Underis customary,

Wood typewriting machine provided with a collatin device such as illustrated in application o. 117,575, filed August 30, 1916.

Fig. 2 is a view of the improved carbon sheet.

The invention is herein illustrated in connection with one of the more modern methods of mechanical bookkeeping, in which the statement sheet 10 is the sheet on which impressions, made by the types 11 through the usual bichrome ribbon -having an upper black stripe 12 and a lower red stripe 13 are printed. .The imprinted impressions ot the types are adaptcd to be printed on one or more record or inner sheets 14, including a ledger sheet, by means of carbon sheets 15,

of which there is one for each inner sheet 14. The statement and record sheets are assembled, usually one by one, upon studs 16 provided on one or both sides of a collatmgtable 17. The sheets 10 and 14, which, as herein illustrated, extend entirely across the table, usually have perforations 18 along one or both sides to fit upon the studs 16,- the provision of the studs and perforations being adapted not only to aline the sheets in the' deslred registration, but also permitting the sheets to be assembled in difi'erent relationships when required, ina manner well understood by those skilled in the art. V In the form of the invention, as herein *disclosed, the carbon sheet 15 has an uncolored ortion 19 or margin at one or both sides, said margin being preferably strengthened by a reinforcing strip 20 which may be a strip of the uncoated carbon paper folded 4 over.

The statement sheet 10, as herein shown, has a number of columns 21 on which digits are usually written in black, and two columns 22 on which the digits are usually written in red. To enable the red digits of the statement sheet 10 to'beim rinted in red on the ledger sheet 14, the b ack or other stale color of'carbon sheet 15 is provided wi a red or other contrasting stripe 23 which is of the same width as the two columns 22, and is adapted to be accurately brought beneath said columns, because the carbon sheet 15 is provided with perforations 24 in its strengthened margin, so located that when the statement sheet 10 is the studs 16, the two columns 22 thereof will fall' precisely over the redstripe 23 of the carbon sheet when that sheet 1s ulined by fitting its perforations 24'over the studs 16.

Since the statement, sheet has several columns 21 to the left of the red digit columns 22 and a single or old balance column 21 to the right of the red digit columns 22, the carbon sheet is provided with a broad black stripe 25 adapted to coincide 'with the lefthand columns 21 of the led er, when the sheets are alined as'aforesai and .with a narrow right-band black stripe 26, which is When the sheets have been alined by the studs 16, the feed rolls 27 ma be thrown on to-clamp the sheets to the posed as thcy are upon each ot er, and t en the handle 28 may e'operated to withdraw the studs 16 from the perforations.

All of the sheets are fed, line by line, around the platen in the usual manner, as the Writing roceeds, the machine being provided with t 'e bichrome ribbon 12, 13, which may automatically type all, of the added numbers' in black, as well as the miscel- ,laneous data that relatos to such numbers,. and may also type the subtracted numbers' in red.

Hence, when the typin is finished, both the outer and inner wor -sheets show the added numbers in black and the subtracted numbers in red. The carbon sheet is ref erably provided with a designation op" at one end 29, so that the operator will not, by mistake, place the other end up and thereby bring the red stripe out of register with the' corresponding columns on the worksheets.

For the purpose of making the alinement very exact, the statement sheet'is frequentl made in the form herein illustrated, with perforations 18 at eaoh margin thereof. In order to enable the statement sheet to be sentto the customer without the stud-fitting pcrforations 18, which are somewhat unsightly to the customer, the statement sheet is usually provided with a row of fine erforations 30, at each side, so that the ges 31 of the statement in which the large peraten, su erthe right-band edge 31 is torn off, the right hand or old balance column 21 will be torn ofi' therewith. The sheets are usually made to have this column torn off, because that column is frequently misleading to .the customer, and is usually a mere incident to the system of bookkeepmg used.

Variations may be resorted to within the scope of the invention, and Portions 'of the improvements may be used without others.
